... Upper Mantle Olivine • Olivine – Thought to be about 10-12% Fe in upper mantle • At pressures around the 410-km discontinuity, Fo-rich olivine transforms to a ccp structure called wadsleyite. • Iron rich olivines do not undergo this transformation. At higher pressures, both the Fa-rich olivine and ...
